WebErythropoiesis can be seen as erythropoietic islands, where cells of the erythropoietic series are seen surrounding a macrophage. The macrophage is referred to as the nurse cell, providing nourishment to the maturing cells. The macrophage also engulfs defective erythroblasts as well as the extruded nuclei from late normoblasts.

Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell.

Erythropoietin is an essential hormone for red blood cell production. Without it, definitive erythropoiesis does not take place. Under hypoxic conditions, the kidney will produce and secrete erythropoietin to increase the production of red blood cells by targeting CFU-E, proerythroblast and basophilic erythroblast subsets in the differentiation.
